The Science Behind the STEM

The chemistry between the dish soap and the fat in the milk makes the magic happen.  Milk is made up of vitamins, minerals, proteins and fats. When the soap is added to the milk, the protein and fats are broken apart. The soap heads for the fats creating the cool bursting of color. All the fat molecules have been found when there is no more movement.
